I bought a moonlite CR2, one of the best around. I got it second hand for $200 which is a bargain, they normally sell new for probably around $350-$400 and you'll have to bring it into Australia yourself.
But it's worth it for me, the dual rate focuser is superb - the fine focus knob has an 8:1 ratio and means you can turn in tiny increments to get the sharpest focus.
I've also got it setup with a homemade motor (thanks Rajah!) so it can be turned with a handheld unit, which I use for imaging.

Whatever you get, the crayford is a huge improvement over the standard R&P.
